Тестирование кабелей 101: There's No Gain with "Gainers"

In a recent Cable Testing 101 series blog on mixing multimode fiber types, we covered the considerations surrounding mixing legacy 62,5 micron (µm) OM1 fiber with today's laser optimized 50µm OM3 and OM4 fiber and highlighted the "gainers" that can happen when transmitting from a smaller 50µm fiber core to a larger 62,5µm fiber core.

Understanding POH: The Power Behind HDBaseT Technology

 Last month we posted a blog about HDBaseT that explained the application and how testing isn't really any different since standards-based Category 5e, 5 or 6A will support it. But maybe you've also heard about power over HDBaseT, or POH, and you're wondering how that differs from power over Ethernet (PoE).

All About Alien Crosstalk Measurement

Alien crosstalk is a relatively new measurement that’s widely misunderstood. I’m often asked why it’s an important measurement and if it’s required to be measured by the standards. Also misunderstood is the sampling criteria for alien crosstalk measurements, which are applied so that not all links have to be tested?
